Cheap Flights Madrid to Santiago de Chile: Long-Haul Done Right

Check live Madrid–Santiago fares on TopTravelCentre →

Cheap flights from Madrid to Santiago de Chile start from about €600–750 round trip when you book 3–5 months out and dodge the southern summer. This is one of the longest nonstop corridors out of Spain — about 13 and a half hours — so the choice between a nonstop and a cheaper one-stop genuinely matters. Compare both on TopTravelCentre.

Route basics

• Nonstop flight time: around 13 hours 30 minutes.
• Departure: Madrid Barajas (MAD).
• Arrival: Santiago Arturo Merino Benítez (SCL), about 20 km from the city centre.
• One-stop alternatives: São Paulo, Buenos Aires or Bogotá — total 17–22 hours.

When to fly and when to book

Chile’s seasons are inverted relative to Europe, which creates clear fare windows:

• Peak: December–February (southern summer, European Christmas holidays) and Chilean Fiestas Patrias in late September.
• Shoulder: March–May and October–November — good weather for Santiago, Patagonia accessible.
• Cheapest: May–June and August, southern autumn/winter with mild days in the capital.
• Booking window: 3–5 months; holiday-week flights only get pricier as seats sell.

Airports: departure and arrival

Madrid Barajas (MAD): intercontinental departures concentrate in Terminal 4 (Iberia, LATAM, Air Europa). The Cercanías C-1 train and Exprés Aeropuerto bus connect to Atocha in 30–40 minutes. Arrive 3 hours before this one — it’s a 13-hour flight and the cheap seats go to those who board.

Santiago SCL: modern and efficient, 20–25 minutes from the centre by taxi, rideshare or the new metro link. Immigration is orderly but slow at peak arrival banks; have your entry paperwork ready. If Patagonia is next, note domestic flights to Punta Arenas often leave early morning — consider an airport hotel.

Five tips that actually save money

1. Exploit the inverted calendar. European summer is Chilean winter — flying Madrid–Santiago in June–August means low fares and mild, rainy-day Santiago weather. Ski season at Valle Nevado is right there.

2. Price Air Europa and Avianca first. These two most often carry the aggressive fares on this corridor; Iberia’s nonstop then has to respond.

3. Depart midweek. Tuesday and Wednesday starts consistently beat weekend fares on the Europe–South America corridors.

4. Weigh a São Paulo split. Flying to São Paulo and connecting onward is sometimes cheaper than the through fare — compare multi-city options on TopTravelCentre.

5. Think open-jaw if Buenos Aires tempts you. Into Santiago, out of Buenos Aires (or reverse) often prices close to a round trip and covers two countries. Our Spanish-language Madrid–Santiago guide covers more route detail.
